Fabrication and Characterization of a Hydrogel Absorbent for the Simultaneous Removal of Dye and Heavy Ion Metal From Water
, M.Sc. Thesis Sharif University of Technology ; Pircheraghi, Gholamreza (Supervisor)
Abstract
In recent years, environmental concerns regarding the removal of pollutants such as organic dyes and heavy metals from water sources have increased significantly. In this regard, hydrogels based on natural polymers have attracted considerable attention for water treatment applications due to their biodegradability, low toxicity, and desirable stability. Hydrogel beads, with their highly porous structure, provide high adsorption capacity and rapid adsorption kinetics. In this study, hydrogel beads based on alginate and polyvinyl alcohol (PVA) polymers were fabricated as mixed and hybrid composites in the presence of zeolitic imidazolate framework (ZIF-8) and diatomite fillers. For this...
